• A 4700 system with 12 mm minimum object resolution and two channels disabled has a minimum object
sensitivity of:
12 mm + 6.25 mm + 6.25 mm = 24.5 mm (0.96 inches).
If the size of the object detected by the 4700 system increases, the minimum safe distance must
increase. Use the minimum object sensitivity given in
determine the new figure to use when computing the safety distance.
